Exocrine Glands: Unicellular and Multicellular Glands

2025
Exocrine glands are classified as unicellular and multicellular. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestines. On the other hand, multicellular exocrine glands develop as secretory sheets, like the internal lining of the abdomen or chest. Such secretory sheets release their secretions directly into the lumen of these organs. In addition, some multicellular glands have deep-seated secretory units to...

The transparent C. elegans intestine can serve as an "in vivo tissue chamber" for studying apicobasal membrane and lumen biogenesis at the single-cell and subcellular level during multicellular tubulogenesis. This protocol describes how to combine standard labeling, loss-of-function genetic/RNAi and microscopic approaches to dissect these processes on a molecular level.

The Tree of Life - Bacteria, Archaea, Eukaryotes

The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both extant and...
FAQs
Cell polarization establishes directional organization within the cell, while targeted membrane trafficking delivers membrane components to appropriate regions. Their coordination helps organize the developing tubular compartment rather than allowing membrane growth to occur randomly. In developmental biology, this relationship explains how a cell can establish specialized membrane domains and maintain the spatial organization required for tubular morphogenesis.
Cytoskeletal remodeling provides an internal framework that can change as the cell’s shape and membrane architecture develop. By coordinating with polarization and membrane trafficking, the cytoskeleton supports controlled shaping of the emerging lumen and surrounding cellular structures. Studying this coordination helps researchers connect intracellular architecture with the physical changes that produce specialized tubular forms.
Controlled lumen expansion allows the hollow compartment to develop with regulated size and shape instead of undergoing uncoordinated enlargement. This process must remain integrated with membrane organization, polarization, and cytoskeletal changes. Its importance extends beyond lumen formation because the resulting geometry influences how the cell creates and maintains a specialized tubular compartment during developmental processes.
The process provides a simplified cellular context for examining how membranes and internal structures become organized during tube formation. By focusing on events within one cell, researchers can investigate the coordination of polarization, trafficking, cytoskeletal remodeling, and lumen shaping as connected processes. These principles contribute to broader explanations of tubular architecture in developing biological systems.
This model helps researchers examine how cells generate specialized tubular compartments and organize their membranes during development. The resulting insights are relevant to epithelial morphogenesis and organ formation, where tubular structures contribute to tissue architecture. It also offers a framework for considering how failures in cellular organization may lead to developmental abnormalities affecting tissue structure and function.
Abnormal tube development can disrupt tissue structure and function, making this process relevant to congenital disorders. Studying unicellular tubulogenesis clarifies how polarization, membrane trafficking, cytoskeletal remodeling, and lumen shaping contribute to normal tubular organization. Developmental biology research can therefore use this cellular context to relate defects in intracellular architecture to broader problems in organ and tissue formation.
